Because capital is an expression of power beyond material needs/wants, and even government can’t effectively govern a class of people that have enough capital to bribe officials en masse to literally bend the laws and regulations to their wills, including to make their bribery perfectly legal as they succeeded in doing here.

That’s why fiscal conservatives were so aroused by the idea of making government, the government that is supposed to protect the citizenry from the whims of those with more power, “small enough to drown in the bathtub.” They succeeded. Our government is subservient to Wall Street’s dictates because we let a few citizens accumulate enough, and shrunk government oversight enough, to turn it into just another acquisition to manipulate to maximize short term private profit.
